Which of the following parasites' eggs hatch and migrate into the nasal chambers and sinuses?
A
Taenia solium
B
Syngamus trachea
C
Oestrus ovis
D
Ascaris lumbricoides
Verified step by step guidance1
Step 1: Understand the life cycle and infection route of each parasite listed to determine which one involves egg hatching and migration into the nasal chambers and sinuses.
Step 2: Recall that Taenia solium is a tapeworm whose eggs hatch in the intestine, not the nasal area, so it can be excluded.
Step 3: Know that Syngamus trachea is a parasite of birds that infects the trachea, but its eggs do not hatch and migrate into nasal sinuses in mammals.
Step 4: Recognize that Oestrus ovis, also known as the sheep nasal botfly, lays larvae (not eggs) that hatch and migrate into the nasal passages and sinuses of sheep, causing myiasis.
Step 5: Understand that Ascaris lumbricoides eggs hatch in the intestine and larvae migrate through the lungs but not into nasal sinuses, so it is not the correct answer.
